    • A first signal (V.sub.1) related to FET drain to source voltage and a second signal (V.sub.2) related to FET source current are compared and the FET (11) is turned off when the first signal exceeds the second signal by a predetermined amount. This corresponds to turning the FET off whe the drain to source on resistance of the FET exceeds a FET on resistance value corresponding to a maximum allowable FET die temperature. Thus the FET is turned off for excessive due temperatures to prevent damage to the FET. A start-up circuit (41, 42) is provided to insure proper initial turning on of the FET, and a short circuit protection circuit (30) is provided for turning the FET off it the source current exceeds some maximum current limit. Accurate, effective monitoring of the FET die temperature is provided without the use of an additional temperature sensing element provided adjacent the FET.
    • 比较与FET漏极至源极电压相关的第一信号(V1)和与FET源极电流相关的第二信号(V2),并且当第一信号超过第二信号预定量时,FET(11)截止。 这对应于当漏极到源极FET的电阻超过对应于最大允许FET管芯温度的FET导通电阻值时关闭FET。 因此,FET会因为过高的温度而关闭,以防止损坏FET。 提供启动电路(41,42)以确保FET的适当的初始接通,并且提供短路保护电路(30)用于使FET关闭,源电流超过一些最大电流限制。 提供对FET裸片温度的精确有效的监控,而不需要使用邻近FET设置的附加温度感测元件。

    • Observing an object within a visual blind spot of a motor vehicle includes using a mirror with at least one motor mechanically coupled thereto. Preferably, a position of the side view mirror can be adjusted by the at least one motor. An object detector detects objects within a visual blind spot of a vehicle. The object detector is operable to provide a detection signal to the at least one motor to adjust a position of the mirror to provide a view of the blind spot to a driver of the vehicle. The view can be toggled between normal viewing and blind spot viewing depending on the detection signal. The view can also be adjusted to track the object.

    • A system and method for charging an auxiliary battery (107) that drives an auxiliary load (109) includes a regulator (111', 223) coupled to an auxiliary battery (107). The regulator (111', 223) provides a charge current (121') that is variable dependent on a parameter of a control signal (203). Preferably, the parameter is an amplitude. A switch (113') provides a coupling and a decoupling between the auxiliary battery (107) and the auxiliary load (109). A control device (115') decouples the auxiliary battery (107) from the auxiliary load (109) via the switch (113'), and then provides the control signal (203) to the regulator (111', 223). By effecting this action, the regulator (111', 223) provides the variable charge current (121') to the auxiliary battery (107) dependent on the amplitude of the control signal (203).
